4. Check to see that each knob insert (4) is securely fastened to the ORION input and vent valve shaft (11).
If it is loose, re-tighten the set screws (23) with the .061" hex wrench.
5. Close the input valve by turning the knob insert (4) clockwise until you feel the valve needle seat on the
O-ring (valve is now in closed position).
6. Rotate gear(s) (small gears with 18 teeth) on isolation valve(s), counter clockwise (gear[s] will rotate
towards valve body) until they stop. Then rotate each gear clockwise 1/2 turn to open isolation valves.
7. Turn the supply pressure regulator to increase the supply pressure to between 80% and 100% of
customers line pressure (ORION-2C or ORION-3A: maximum 3000 PSI; ORION-2D: maximum 300
PSI).
8. Open the VENT valve to atmosphere to release line pressure, then close the VENT valve.
9. Slowly open the input valve by turning the knob insert (4) counter-clockwise until you notice the input
pressure gauge pressure increase. Then turn the knob insert (4) slightly clockwise until the pressure stops
rising.
10. Mark a radial line at the 12 o’clock position on the knob insert.
11. Turn the knob insert (4) clockwise to move the mark to the 6 o’clock position.
12. Turn the locknut (2) counter-clockwise until it contacts the bottom of the stop washer. Tighten the set
screw (34) on the locknut with the .050" hex wrench.
13. Install the input valve knob (3) on the knob insert (4) and engage its gear (5) with the smaller isolation
valve gear (6). Turn the knob clockwise until the isolation valve is slightly snug.
CAUTION: do not use excessive torqure when doing this. The seat may be damaged .
14. Remove the input valve knob (3). Align the set screws (25) with the indentations on the knob insert.
Install the knob on the knob insert (4) while engaging the knob gear (5) with the isolation valve gear (6).
15. Tighten the set screws (25) with the .061" hex wrench. The input valve is now adjusted.
16. To adjust the VENT valve (ouput). Close the input valve by turning the output valve knob clockwise.
17. Close the VENT valve knob insert (4) clockwise until slightly snug.
18. With the supply pressure at customer’s 100% line pressure (ORION-2C or ORION-3A: maximum 3000
PSI; ORION-2D: maximum 300 PSI). Open the COARSE valve until the indicated pressure stabilizes
and then close the COARSE valve.
19. Slowly turn the VENT valve (ouput) knob insert (4) counter-clockwise until you hear flow from the VENT
valve, then turn the knob insert (4) slightly clockwise until the pressure stops decreasing.
20. Repeat steps 10 - 15 for the VENT valve, replacing the term "input valve" with "output valve."
2.10 MPV-10K Manifold - Valve Adjustment Procedure (Customer Installation)
(MPV-10K - Refer to the List of Parts - Table 2-4 on page 19, and Figure 2-12 on page 21)
NOTE: Customer must supply, as a minimum, input supply pressure with a supply guage and pressure regulator.
Tools required: hex wrench (.050")
hex wrench (.061")
1. Turn the supply pressure regulator off.
2. If not already done, remove the MPV-10K knob (15) using the .061" hex wrench.
3. Using a .050" hex wrench, loosen the set screw (13) on the MPV-10K valve locknut (12) and turn
locknut clockwise until it stops.
4. Align the set screws (16) with the indentations on the valve needle (3 or 6). Install the knob using the
.061" hex wrench.
5. Turn the supply pressure regulator, to increase the supply pressure to between 80% and 100% of
customer’s line pressure (maximum 10,000 PSI). Let system settle for 5 minutes.
NOTE:Some valves may not be recommended for 10000 PSI, because of O-ring material selection. See Section 2.2 on
page 2.
6. Slowly open the MPV-10K valve by turning the knob (15) counter-clockwise until you notice the
pressure of the input pressure guage increase. Then turn the knob slightly clockwise until the pressure
stops rising.
